Like its predecessor, No Boundaries includes transcriptions for five pianos as well as duos and trios featuring various combinations of the siblings. The repertoire includes Gershwin's Rhapsody in Blue, Stravinsky's The Firebird, and a medley of the "Simple Gifts" sections from Copland's Appalachian Spring and the "Going Home" section from Dvoršk's Ninth Symphony ("From the New World").
Driven by the publicity around the new release—the Browns have appeared on Entertainment Tonight, The View, and other TV shows in recent weeks— the pianists' self-titled first album has surged back onto the chart, reaching number two this week.
Pianist Lang Lang's Memory dropped from number one to number three, while pianist Yundi Li's Vienna Recital jumped from number 15 to number four, its peak position in eight weeks on the chart.
Other new entries included Plšcido Domingo's Italia, Ti Amo, a collection of Italian popular songs, at number 14; and a recording of Brahms' First Piano Concerto by Simon Rattle and the Berlin Philharmonic, with Krystian Zimerman as soloist, at number 16.
Andrea Bocelli's Amore remained at number one on the classical-crossover chart. The Los Angeles Guitar Quartet's Spin debuted at number 21, and the Cincinnati Pops' Great Film Fantasies, conducted by Erich Kunzel, entered the chart at number 25.
